Samsung QET 43" Class 4K UHD Commercial LED Display
PRODUCT DESCRIPTION
Samsung QE43T 43" Crystal UHD 4K Commercial Display (LH43QETELGCXXS) - Local Warranty
4K UHD Detail at Close Reading Distance in Retail and Receptions
A 43-inch screen is normally read from two or three metres - a counter-top menu board, a reception directory, a clinic waiting room or a meeting-room display. At that distance 3,840 x 2,160 keeps small type, price lists and appointment lists crisp rather than soft. The QE43T pairs that resolution with a 4,000:1 contrast ratio and a direct-lit LED backlight for even brightness across the panel, plus a 2% haze finish that keeps the picture looking clean under normal interior lighting. Colour gamut is 72%, which is ample for brand artwork and photography.
16/7 Commercial Duty for Shops, Clinics and Offices
Samsung rates the QET series for 16 hours a day, seven days a week - matched to a business that opens in the morning and closes at night, which describes most Singapore retail, F&B, clinic and office deployments. That rating is what separates it from a consumer television used as signage: the panel, power supply and thermal design are specified for the hours it will actually run. If the screen genuinely needs to stay on around the clock, step up to a 24/7-rated display instead of pushing this one past its duty cycle.
IP5X Dust-Protected Chassis for Real Retail Floors
The QE43T carries an IP5X rating for dust ingress, which matters more than it sounds. Retail floors, workshops, warehouses and F&B outlets push dust and airborne grease into every vent, and dust inside a panel is what eventually causes hot spots and fan noise. A sealed chassis also makes the display a safer choice for a shopfront window or a kiosk enclosure where cleaning access is limited. Combined with the 300-nit panel it suits interior positions that are busy but not directly sunlit.
MagicInfo Lite On Board - Plug in a USB Stick and Go
MagicInfo Lite is built into the display on Tizen 4.0 with 8GB of internal memory, so a playlist of images and video can be loaded from a USB stick and scheduled on the screen itself. For a single shop, a clinic reception or a showroom that removes the cost of a media player and a CMS subscription entirely - the person at the counter can update the promotion. An RJ45 port is fitted for network deployments, and two HDMI 2.0 inputs let a laptop or room system share the screen when the signage is not running.

Compatibility & Installation
Mounting
The QE43T uses a 200 x 200mm VESA pattern and weighs 8.4kg, so it works with standard flat and tilting commercial brackets and is light enough for a single installer. The panel measures 963.9 x 558.9 x 59.6mm without a stand. Samsung specifies this model for landscape orientation only, so it is not a candidate for a portrait wayfinding column - choose a portrait-rated display for that. A Samsung STN-L4355F stand is available as an option where the screen needs to sit on a counter or a plinth rather than on the wall.
What it connects to
Two HDMI 2.0 inputs take a laptop, a room system, a set-top box, a camera feed or a media player. One USB port handles local playback from a stick, which is how most single-site deployments load their content. Audio can go out over the stereo mini jack to an amplifier, or play on the built-in 10W + 10W speakers, which are adequate for a reception or a small retail floor. RS232C in on a stereo mini jack lets the display join a control system for scheduled power on and off.
Network and content management
MagicInfo Lite runs on the display itself under Tizen 4.0 with 8GB of internal memory, so no external player or server is needed for straightforward scheduled playback. Load content by USB for a single screen, or connect the RJ45 Ethernet port to manage the display over the network. This model has no built-in Wi-Fi, so plan a data point or a small Ethernet adapter at the mounting position if network management is required. For estate-wide scheduling across many sites, a full MagicINFO server licence can be used.

The same QET platform is also available at 65 inches. Where the position faces daylight or the screen must run around the clock, the 700-nit 24/7 QH43C is the equivalent size in the high-brightness QHC range.

Frequently Asked Questions - Samsung QE43T
Is 43 inches the right size for my space?
It suits a reading distance of roughly two to four metres - counter-top menu boards, clinic waiting rooms, reception directories, lift lobbies and small meeting rooms. If viewers will be eight metres or more away, or the screen is competing with a busy retail floor, move up to the 65-inch QE65T.
What does the 16/7 rating mean, and when do I need 24/7 instead?
Samsung rates the QET series for 16 hours a day, seven days a week, which matches a business that opens in the morning and closes at night. If the screen has to stay on around the clock - transport, healthcare corridors, a 24-hour lobby or a shopfront that keeps running after closing - specify a 24/7-rated display such as the QHC series rather than running this one beyond its duty cycle.
Does it need an external media player?
No. MagicInfo Lite is built into the display on Tizen 4.0 with 8GB of internal memory, so images and video load from a USB stick and play to a schedule with no extra hardware. An external player or a full MagicINFO server is only needed for advanced, multi-site content workflows.
Can I mount the QE43T in portrait?
No. Samsung specifies this model for landscape orientation only. For a portrait wayfinding column or a lift-lobby totem, choose a display Samsung rates for portrait installation, such as a QHC series model.
Is it a touchscreen?
No. The QE43T is a non-touch signage display. For interactive directories or collaboration, look at a touch-enabled model or add a third-party touch overlay sized to a 43-inch panel.
What does IP5X actually protect against?
IP5X is a dust ingress rating - it means the chassis is protected against dust to the level where any ingress will not interfere with operation. It is not a water rating and does not make the display suitable for outdoor or wash-down use. In practice it helps in shops, workshops, warehouses and F&B outlets where airborne dust and grease shorten the life of an unsealed panel.
What do the letters in QE43T and LH43QETELGCXXS mean?
QE is the entry commercial signage family, 43 is the screen size in inches and T is the generation. In the full part number LH43QETELGCXXS the trailing XXS identifies the Singapore market model, which is what SourceIT supplies with a local warranty and a Singapore power cord.
What warranty and invoicing do I get from SourceIT?
Every unit is supplied with the local Singapore warranty and a GST invoice, which is what your finance team needs for input tax claims and what facilities needs for a valid service entitlement in Singapore.
